Checkpoint Alpha functioned as an assembly point established by the future 501st Legion in proximity to a crashed Techno Union ship during the Battle of Geonosis. In order to provide support during the conflict, the clone troopers positioned medical and ammo droids in the surrounding vicinity. After a Clone jet trooper discovered a significant holocron that had been dropped by a dead Geonosian, his commanding officers instructed him to deliver it to Checkpoint Alpha.
